Abstract: PROBLEM TO BE SOLVED: To surely and accurately enable the supplying of molten metal in a short time and to enable the discharge of the whole molten metal in a ladle for supplying molten metal after completing casting work by discharging the molten metal in the ladle for supplying molten metal after inserting the lower part of the ladle for supplying molten metal into a tilted injection sleeve. SOLUTION: The ladle 100 for supplying molten metal is shifted to a holding furnace while holding the tilted attitude at the upward side of a molten metal hole till forming as the almost same angle as the inclining angle of the injection sleeve and the lower part of an introducing tube 112 is dipped into molten metal surface in the holding furnace. The dipped depth is made so that the lower end of the introducing tube dips into about 5-20 mm from the molten metal surface and the bottom surface plate 110a is not brought into contact with the molten metal surface. Therefore, the drop and mixing of the stuck material on the injection sleeve can be prevented and the cleanliness of molten metal can be held to high degree.  Thereafter, while measuring the weight with a weight detecting means 210, an evacuating device 130 is driven till reaching a prescribed weight to suck the gas in the ladle 100 for supplying molten metal.

Filed: 1988-04-28
Abstract: PURPOSE:To improve sensitivity, to prevent fogging from being generated, and to obtain a sharp image by applying whole image exposure on an image carrier by light whose wavelength area is less than 620nm between a destaticizing stage and an electrification stroke. CONSTITUTION:A light emitting diode is used as a whole image exposure means 3, and it is constituted so that the wavelength less than 620nm can be emitted. And at the time of forming an image, the whole image exposure is applied on the surface of an organic photoconductor 1a by the light emitting diode between static elimination by a static elimination lamp 11 and electrification by an electrification charger 2. Thereby, the organic photoconductor 1a is pre- excited, and the generating ratio of an electric charge can be increased, and also, the trap of the electric charge in the neighborhood of the interface of the electric charge generating layer and the electric charge transfer layer of the organic photoconductor 1a is decreased, and the sensitivity of a 1/10 exposure quantity is increased. In such a way, it is possible to prevent the fogging due to the splash of a developer 5a from being generated, and to form a satisfactory image.

Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To decrease parts, to simplify control and to facilitate maintenance by providing the device with a raw liquid sampling means which is arranged with its front end near the inside base of a metering tank and is communicated at its other end with a mixer, supplying a compressed gaseous pressure to this metering tank and transferring the raw liquid in the metering tank to a mixer via this raw liquid sampling means. SOLUTION: When the liquid level of the dilute chemical soln. S1 of a diluting tank 18 falls down to L1 and when this level is sensed by a liquid level sensor 19, a valve 16 is opened to supply the diluting water from a diluting water source 17 to the diluting tank 18 through a mixing machine 14, etc. The connection port of a three-way selector valve 7 is changed over simultaneously therewith to force feed the compressed air from an air supply source 10 into the metering tank 5 and to shut off the passage between a raw liquid tank 1 and the metering tank 5. As a result, the pressurized raw liquid S0 in the metering tank 5 is supplied from a collector nozzle 11 to the mixing machine 14, where the raw liquid is continuously mixed with the diluting water and the mixture is admitted into the diluting tank 18. When the liquid level of the diluting tank 18 rises to a level H1 , an automatic stop valve 16 is closed to stop the supply of the diluting water to the diluting tank 18.

Title: Picture processing method
Inventor: SHISHIZUKA JIYUNICHI
IPC: G06T11/60
Filed: 1989-04-25
Abstract: PURPOSE:To accurately segment picture data in the short time without requiring human intervention by converting color picture data to hue data, luminance data, and saturation data and using hue data or saturation data. CONSTITUTION:Color picture data is converted to hue data, luminance data, and saturation data of three attributes of color, and hue data or saturation data is used to segment picture data. For example, a square area abcd designated by a mouse is subjected to raster scanning, and luminance data RGB of a picture element G(i,j) is converted HLS (hue, luminance, and saturation), and the hue out of three attributes of color is defined as H(i,j). The picture element G(i,j) is displayed when the difference between H(i,j) and the hue Hk of a representative color of the segmented picture is smaller than a certain determined value H0, but it is not displayed when this difference is larger than H0, and the accuracy of picture segmentation is controlled by the value H0. Thus, the picture is accurately segmented even when the color of the picture to be segmented resembles that of the ground picture.

Title: Washing machine
Inventor: OKAZAKI KIYOSHI
IPC: D06F39/02
Filed: 1989-04-26
Abstract: PURPOSE:To supply a detergent without a bad condition, such as its dilution or its wasteful discharge by a method wherein, at the feeding time of the detergent, when it is detected that a waterlevel in a washing receptacle reaches a setting waterlevel, the detergent is fed with water supplied after the water in the washing receptacle is drained as far as a specified waterlevel. CONSTITUTION:At the rear part of a top panel 2, a detergent-feeding device 7 having a detergent-storing box 5 and a lid 6 is located and a waterlevel sensor 8 detecting a waterlevel stored in a washing receptacle is also located. The detergent-feeding device 7 sends the detergent held in the detergent-storing box 5 onto a supplying waterway facing into the washing receptacle, by a detergent-feeding member, and feeds its detergent into the receptacle with water supplied from a feed valve. According to an output signal detected by the waterlevel sensor 8, electricity is applied so that a drain valve can drain as far as a waterlevel lower by one step when it is detected that the waterlevel in the washing receptacle reaches a setting level. That is to say, when the waterlevel in the washing receptacle reaches the setting level of 'high', the detergent is fed with water supplied after the water is drained as far as a waterlevel of 'middle', and thus the wasteful discharge of the detergent is prevented.

The copper is taken up as the copper foil 4. In such a case, the carbon content in the copper foil 4 is confined to <=18ppm by controlling the amt. of the glue as the org. matter in the electrolyte 3. The resulted copper foil 4 is heat treated at 100 to 300 deg.C in a gaseous nitrogen atmosphere.  The copper foil which is recrystallizable at a low temp. of about 120 deg.C, has the excellent performance compared with the conventional rolled copper foil and has the broad width hardly producible from the rolled copper foil is thus stably and inexpensively produced.

Abstract: PURPOSE:To enable semiconductor packaging to be automated by performing soldering passive-type chip parts at an opposite side to a mounting surface of a semiconductor chip of a circuit substrate and a lead for external connection using a non-washing type flux and then keeping the flux which is adhered to and remaining at the soldering portion as it is. CONSTITUTION:Passive-type chip parts 4 at a mounting-surface side of a semiconductor chip 2 of a circuit substrate 1 is soldered by using a normal flux. On the other hand, passive-type chip parts 4' and a lead 6 for external connection are soldered by using a non-washing type flux 9. Therefore, even if mounting of the semiconductor chip 2 and semiconductor sealing for protecting the chip 2 are performed previously and then the passive-type chip parts 4' on the opposite side surface and the lead for external connection 6 are soldered, a resin 8 for exterior finish can be coated since the flux 9 needs not be washed at the time of soldering, thus enabling an automatic packaging machine with an automatic substrate supply mechanism to be used.
